Steel bar part welding and positioning device for building construction

Abstract

The invention relates to a steel bar part welding and positioning device for building construction so as to solve the problems that in the welding process of steel bar electroslag pressure welding, a device is frequently disassembled, different-diameter steel bars are not coaxial after being installed and clamped, and the quality problem after steel bar welding is caused by operation of building workers during pressurizing and upsetting. The steel bar part welding and positioning device comprises a fixing rod with the axis vertically arranged, a first arc-shaped frame and a second arc-shaped frame are connected to the fixing rod, a first centering and clamping mechanism, a welding distance adjusting mechanism and a control system are arranged on the first arc-shaped frame, a second centering and clamping mechanism is arranged on the second arc-shaped frame, and a conductive agent box opening and closing mechanism is arranged on the fixing rod. By adjusting the welding distance adjusting mechanism, the problem that the welding distances of steel bars with different diameters are different is solved, a motor rotating speed switch is adjusted, the pressurizing and upsetting time of the steel bars with different diameters is adjusted, and in the pressurizing and upsetting process, the steel bar welding quality problem caused by the operation problem of workers is effectively avoided.

Description

technical field [0001] The invention relates to the field of steel bar welding, in particular to a welding positioning device for steel bar for building construction. Background technique [0002] In the welding of steel bars in the construction field, commonly used steel bar welding methods include flash butt welding, arc welding, electroslag pressure welding, resistance spot welding and steel bar pressure welding. Electroslag pressure welding is mostly used for vertical steel bars in cast-in-place reinforced concrete structural members. Take it long. The use method of prior art electroslag pressure welding: put a small piece of conductive agent (steel wire bead, electric welding rod, etc.) The arc is ignited and burned by the circuit. After the slag pool is formed, the steel bar is melted and the arc is stabilized for a certain period of time, while the power is turned off, the manual pressurization mechanism is used for pressurized upsetting to remove slag inclusions and...
